A calorie-free milkshake? Suppose a cylindrical glass with a diameter of m and a height of m is filled to the brim with a 400-Cal milkshake. If you have a straw that is 1.1 m long (so the top of the straw is 1 m above the lip of the glass), do you burn off all the calories in the milkshake in drinking it? Assume that the density of the milkshake is 1 g/cm3(1 Cal = 4184 J).

QUESTION:
A calorie-free milkshake? Suppose a cylindrical glass with a diameter of m and a height of m is filled to the brim with a 400-Cal milkshake. If you have a straw that is 1.1 m long (so the top of the straw is 1 m above the lip of the glass), do you burn off all the calories in the milkshake in drinking it? Assume that the density of the milkshake is 1 g/cm3(1 Cal = 4184 J).
ANSWER:
Step 1 of 3
is the density of the milk shake
is the lifting distance and because the top of the straw is above the bottom of the glass is equal to
Boundaries
,
is the cross sectional area of the glass with the height
